本文设计一个基于多点触摸、手势识别等技术的新型投影系统,通过摄像头捕捉手指触摸或激光笔照射投影屏幕时所反射的红外光,将信息传递到图像处理模块,并对其进行多点定位和分析,判断出旋转、缩放等操作意图后,将处理结果以标准形式传输到相应的应用程序,并做出相应的操作。系统构建所需的设备简单、价格低廉。测试结果显示：系统反应灵敏,能满足应用需求。%The paper designs a new projection system which is based on the theory of Multi-Touch and gesture recognition. When fingers touch or laser pointers irradiate the screen, the system captures the reflected infrared light by camera and transmits the information to the image processing module to do some multi-point positioning and analysis to determine the intention such as rotation, zoom or others. The results will be transmitted to the appropriate application program by a standard form, and it will have the computers done some appropriate actions. The equipmenst used to build the system are simple and inexpensive. The test results showed that the system is responsive and it can meet the needs of the general presentation.
